Unable to install karpenter using terraform EKS Module v18.19.0

[sriram0721]

##Version
eks 1.21
Terraform eks module - 18.19.0

We are trying to install karpenter on eks which is provisioned through terraform aws eks module (18.19.0) . As per karpenter docs, it states eks version to be <18 . When i tried to install it on my cluster, i faced an error

│ 12: role = module.eks.worker_iam_role_name
│ ├────────────────
│ │ module.eks is a object, known only after apply
│
│ This object does not have an attribute named "worker_iam_role_name".

When i referenced with tf docs, there is no output as "worker_iam_role_name" for version 18+ .
Do i need to use older eks module versions or is there any work around for this ?

@sriram0721 you can use this mine tf which is new, the one in docs are using deprecated modules.

#1634

hey thanks for that it worked!. btw, when i try to test it out by scaling a deployment, it does provisions the node. However, the node is not getting attached to the cluster. its in not ready state because of some taints. Any idea on this @pratikbin ?

We should probably update our docs to use v18 of the EKS Terraform module.
